Improvement in skylight-bars



UNITED STATES PATENT OFFICE.

CHARLES SELLMAN, OF NEW YORK, N. Y.'

IMPROVEMENT IN SKYLIGHT-BARS.

Specification forming part of Letters Patent No. 146,556, dated January 20, 1874; application filed December 6, 1873.

To all whom it may concern:

. Be it known that I, CHARLES SELLMAN, of the city, county, and State of New York, have `invented a new and useful Improvement in `Skylight-Bars, of which the following is a specification:

My invention is an improvement in that Y class of skylightbars formed of sheet metal 5 and its object is to simplify the construction, and at the same time strengthen or stiifen the same; and it consists of a vertical central portion having at a suitable point below its uppermost edge a horizontal portion, forming a sup- Y port for the glass each side of the vertical portion, and at the bottoni of the same a V-shaped double gutter for reception of the dripping `water condensing on the inside of the glassplates, the spread of the gutters being each v side of the vertical central portion.

is usually formed of one piece of metal, including the supporters for the glass and the gutters.

This bar In the accompanying drawings, Figure l represents a side elevation of a skylightbar.

Fig. 2 represents an end view of the same at A B, Fig. 1.` Fig. 3 represents a transverse section of the same on line C I), Fig. l. Fig.

4 is an end view, similar to Fig. 2, representinga modification of the same; and Fig. 5 is fasectional view similar to Fig. 3 of the modi` cation shown in Fig. 4.

a represents the central vertical portion; I), the supporters for the glass-plates5 c, the gut ters. These form the three divisions or main portions of the bar, and when constructed of one piece of metal are formed as follows: Be-

ginning at el the sheet runs down to e, and is y l `-there bent at an acute angle, thence upward,

forming one side of vertical portion a to f. It

is there bent completely over and, running downward, forming the other side yof vertical portion a to e. Again bent, it runs oiI' at an i acute angle upward to g, and therehbent coin pletely over, it is run down outside the gutters to e, and upward to d, turning and overlapping to form a finish in completion. The two acute angles above mentioned form the gutters c. The glass-supports b are then formed p as follows: Slits are cut at -b b', Fig. l, and the portion between `the slits is then beat or` pressed down until it becomes dat, as shown in Fig. 3. i

The niodiiied foi-n1 shown in Figs. 4 and 5 diifers only from the above in the fact of the plate being discontinued underneath the gutters from g down to e and up to d at the finish; otherwise it is the same, but the omission of the said part renders it weaker, and such bar is only serviceable for lighter skylights, and for such it is somewhat cheaper and usually suflicient. i

At j rivets are used to unite both sides of the vertical portion and complete its construction7 rendering it perfectly stiff and strong. Z1. y

represents a seinicircular cap, covering over the putty and the `joints, and it is` intended that the whole interior underneath the saine shall be lled up entirely with putty or cement to make the joint tight, secure the glass, and

prevent water passing through to the interior beneath the glass. y

The bar, constructed as herein described,`is

stron ger and cheaper than those heretofore in use, inasmuch as it lessens labor and requires less material, while at the same time it is much` lighter and stiffer.

y What I claim as new, and desire to secure` by Letters Patent of the United States, is`

The skylight-bar composedof the portions` p a, b, and c, when constructed `substantially in the manner and for the purpose as described and set forth.

` y CHARLES SELLMAN.
